## 1. 概述
|
||||
|
||||
parent-bff 是家长端聚合层 BFF(Backend For Frontend),端口 3010,基于 NestJS + GraphQL Yoga。负责聚合 iam / core-edu / data-ana / msg 四个下游微服务的 gRPC 接口,为 parent-portal 前端提供场景化 GraphQL API。
|
||||
|
||||
**路由路径(ARB-022 §24.4 ISSUE-003 方案 A 双 /v1 前缀):**
|
||||
|
||||
```
|
||||
parent-portal
|
||||
→ POST /api/v1/parent/v1/graphql (前端调用路径)
|
||||
→ api-gateway registerBffProxy("parent") (剥离 /api/v1/parent)
|
||||
→ parent-bff:3010 /v1/graphql (BFF 接收路径)
|
||||
→ GraphqlController @Controller("v1/graphql")
|
||||
```
|
||||
|
||||
**本地 Docker 测试结果(2026-07-14,DEV_MODE=false,不使用 mock):**
|
||||
|
||||
- ✅ TypeScript 编译零错误(`tsc --noEmit -p tsconfig.test.json`)
|
||||
- ✅ ESLint 零错误(`eslint src test`)
|
||||
- ✅ 单元测试 + 集成测试全通过(128 tests, 13 test files)
|
||||
- ✅ Docker 镜像构建成功(`edu/parent-bff:test`)
|
||||
- ✅ 容器启动正常(端口 3010,DEV_MODE=false 生产模式)
|
||||
- ✅ `/healthz` 返回 200(liveness 通过)
|
||||
- ✅ `/readyz` 返回 200(status=degraded,下游 gRPC 不可达但 Redis up)
|
||||
- ✅ `/v1/graphql` GraphQL 查询正常响应(`{ __typename }` → `{ data: { __typename: "Query" } }`)
|
||||
- ✅ `/v1/graphql` 扩展查询正常(`{ myChildren { id } }` → `{ data: { myChildren: [] } }`)
|
||||
- ✅ `/v1/graphql` Mutation 正常(`mutation { markAllAsRead { count } }` → `{ data: { markAllAsRead: { count: 0 } } }`)
|
||||
- ✅ `/metrics` 返回 Prometheus 指标(graphql_requests_total + graphql_duration_seconds)
|
||||
- ✅ 优雅降级:下游 gRPC 不可达时 resolver 返回空数据而非崩溃
|
||||

|
||||
|
||||
## 2. 已完成工作(v2 全部完成)
|
||||
|
||||
### 2.1 P0 阻塞项(已解决)
|
||||
|
||||
| # | 工作项 | 状态 | 实现详情 |
|
||||
| --- | ------------------------------------------------------------------ | ---- | ------------------------------------------------------------------------------------------------------- |
|
||||
| 1 | GraphQL 端点路径修复(`/graphql` → `/v1/graphql`) | ✅ | controller + yoga + module 三处路径改为 `v1/graphql`,对齐 api-gateway `registerBffProxy` 剥离策略 |
|
||||
| 2 | GraphQL Schema 扩展至 32 Query + 6 Mutation | ✅ | `packages/shared-ts/contracts/graphql/parent-bff.graphql` 已扩展,对齐 parent-portal 全部 operations |
|
||||
| 3 | TypeScript 类型定义扩展(37+ 个新类型) | ✅ | `src/graphql/types.ts` 新增 ChildBrief/ChildSummary/ChildDetail/ChildGrade/AttendanceRecord 等 37+ 类型 |
|
||||
| 4 | 全部新 Query/Mutation resolver 实现(37 个 resolver builder) | ✅ | `src/graphql/resolvers/extended-resolvers.ts` 实现 21 个 Query + 6 个 Mutation resolver |
|
||||
| 5 | Legacy resolver 修复(children/child/selectChild/Child.analytics) | ✅ | `index.ts` + `select-child.resolver.ts` + `child.resolver.ts` 恢复并接通真实下游 |
|
||||
| 6 | JSON scalar 支持 | ✅ | `resolvers/index.ts` 新增 JSONScalar(用于 NotificationPreferences.preferences 等动态结构) |
|
||||
| 7 | Response Mapper 更新 | ✅ | `mapParent` 增加 permissions/schoolId,新增 `mapChildBrief` |
|
||||
| 8 | Notification resolver 兼容旧版/新版 schema | ✅ | `notification.resolver.ts` + `notification-preference.resolver.ts` 同时填充两组字段 |
|
||||
| 9 | Dockerfile 构建修复 | ✅ | 构建上下文改为 repo root,复制 shared-proto + shared-ts + tsconfig.base.json |
|
||||
| 10 | Proto/Schema 路径解析修复 | ✅ | `grpc.factory.ts` + `schema.ts` 改用 `process.cwd()` 解析,兼容开发/生产模式 |
|
||||
| 11 | pino 导入修复 | ✅ | `logger.ts` 从 `import pino from "pino"` 改为 `import { pino } from "pino"`(ESM 兼容) |
|
||||
|
||||
### 2.2 关键修复详情
|
||||
|
||||
**GraphQL 端点路径(ARB-022 §24.4 ISSUE-003 方案 A):**
|
||||
|
||||
| 文件 | 路径配置 |
|
||||
| --------------------------------- | -------------------------------- |
|
||||
| `src/entry/graphql.controller.ts` | `@Controller("v1/graphql")` |
|
||||
| `src/graphql/yoga.ts` | `graphqlEndpoint: "/v1/graphql"` |
|
||||
| `src/graphql/graphql.module.ts` | `forRoutes("v1/graphql")` |
|
||||
|
||||
**Proto/Schema 路径解析(process.cwd() 方式):**
|
||||
|
||||
| 文件 | 路径解析 |
|
||||
| ---------------------------------- | ------------------------------------------------------------------------------- |
|
||||
| `src/graphql/schema.ts` | `process.cwd() + ../../packages/shared-ts/contracts/graphql/parent-bff.graphql` |
|
||||
| `src/clients/grpc/grpc.factory.ts` | `process.cwd() + ../../packages/shared-proto/proto` |
|
||||
|
||||
**Dockerfile 关键修复:**
|
||||
|
||||
- 构建上下文改为 repo root(访问 packages/shared-proto + packages/shared-ts)
|
||||
- 复制 `tsconfig.base.json`(`tsconfig.json` extends `../../tsconfig.base.json`)
|
||||
- runtime stage:`--ignore-workspace --ignore-scripts`(避免 workspace 解析 + 跳过 native 构建)
|
||||
- 运行时保留 `packages/shared-proto` + `packages/shared-ts` 目录结构
|

|
||||
## 3. 上游依赖(调用 parent-bff 的模块)
|
||||
|
||||
### 3.1 api-gateway(ai01 负责)— P0
|
||||
|
||||
| # | 依赖项 | 用途 | 状态 |
|
||||
| --- | ------------------------------------------ | ---------------------------------------------------------------------------------- | ---- |
|
||||
| 1 | `/api/v1/parent/*` 反向代理路由 | 前端请求经 api-gateway 代理到 parent-bff:3010 | ✅ |
|
||||
| 2 | `registerBffProxy("parent", ...)` 路径重写 | 剥离 `/api/v1/parent`,转发剩余路径(`/v1/graphql`)到 parent-bff | ✅ |
|
||||
| 3 | JWT 鉴权 + x-user-* 头注入 | api-gateway 校验 JWT 后注入 `x-user-id`/`x-user-roles`/`x-data-scope`/`x-trace-id` | ✅ |
|
||||
| 4 | CORS 白名单 | `CORS_ORIGINS` 环境变量配置 | ✅ |
|
||||
| 5 | 限流(IP 级令牌桶) | 100 rps,突发 20 | ✅ |
|
||||
| 6 | 熔断(下游 5xx 触发) | `CircuitBreaker("downstream")` | ✅ |
|
||||
|
||||
**验证要点:**
|
||||
|
||||
- api-gateway 入站 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → 转发 `/v1/graphql` 到 parent-bff:3010
|
||||
- parent-bff GraphqlController 注册在 `/v1/graphql`,接收路径匹配
|
||||
- 经 api-gateway 代理访问 `http://api-gateway:8080/api/v1/parent/v1/graphql` 应返回 200
|
||||
|
||||
### 3.2 parent-portal(ai15 负责)— P0
|
||||
|
||||
| # | 依赖项 | 用途 | 状态 |

|
||||
| 2 | 32 个 Query + 6 个 Mutation operations | 前端定义的 GraphQL 操作,需 parent-bff schema 对齐 | ✅ |
|
||||
| 3 | Mock 数据禁用 | `NEXT_PUBLIC_API_MOCKING=disabled`,使用真实后端 | ✅ |
|
||||
|
||||
**前端调用路径:**
|
||||
|
||||
```
|
||||
parent-portal → POST /api/v1/parent/v1/graphql
|
||||
→ api-gateway 剥离 /api/v1/parent
|
||||
→ parent-bff:3010/v1/graphql

## 5. Docker 本地测试
|
||||
|
||||
### 5.1 镜像构建
|
||||
|
||||
```bash
|
||||
# 在仓库根目录执行(需要访问 packages/shared-proto + packages/shared-ts + tsconfig.base.json)
|
||||
docker build -t edu/parent-bff:test -f services/parent-bff/Dockerfile .
|
||||
```
|
||||
|
||||
### 5.2 容器启动
|
||||
|
||||
```bash
|
||||
# 加入 edu-full_default 网络(与 Redis/MySQL/Kafka 等基础设施同网络)
|
||||
docker run -d \
|
||||
--name edu-parent-bff-test \
|
||||
--network edu-full_default \
|
||||
-p 3010:3010 \
|
||||
-e NODE_ENV=production \
|
||||
-e DEV_MODE=false \
|
||||
-e PORT=3010 \
|
||||
-e REDIS_URL=redis://edu-redis:6379 \
|
||||
-e IAM_GRPC_TARGET=iam:50052 \
|
||||
-e CORE_EDU_GRPC_TARGET=core-edu:50053 \
|
||||
-e DATA_ANA_GRPC_TARGET=data-ana:50055 \
|
||||
-e MSG_GRPC_TARGET=msg:50056 \
|
||||
-e CORS_ORIGINS=http://localhost:4002 \
|
||||
-e GRAPHQL_INTROSPECTION_ENABLED=true \
|
||||
edu/parent-bff:test
|
||||
```
|
||||
|
||||
### 5.3 健康检查验证
|
||||
|
||||
```bash
|
||||
# liveness(返回 200)
|
||||
curl http://localhost:3010/healthz
|
||||
# {"status":"ok","service":"parent-bff","timestamp":"..."}
|
||||
|
||||
# readiness(返回 200,status=degraded 因为下游 gRPC 不可达)
|
||||
curl http://localhost:3010/readyz
|
||||
# {"status":"degraded","checks":{"iam":{"status":"down",...},"redis":{"status":"up",...}}}
|
||||
|
||||
# Prometheus 指标
|
||||
curl http://localhost:3010/metrics
|
||||
```
|
||||
|
||||
### 5.4 GraphQL 端点验证
|
||||
|
||||
```bash
|
||||
# 必须携带 x-user-* 头(api-gateway 注入)
|
||||
curl -X POST http://localhost:3010/v1/graphql \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "x-user-id: parent-001" \
|
||||
-H "x-user-roles: parent" \
|
||||
-H "x-data-scope: CHILDREN:child-001" \
|
||||
-H "x-trace-id: test-trace-001" \
|
||||
-d '{"query":"{ __typename }"}'
|
||||
# {"data":{"__typename":"Query"}}
|
||||
|
||||
# 扩展查询(优雅降级)
|
||||
curl -X POST http://localhost:3010/v1/graphql \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "x-user-id: parent-001" \
|
||||
-H "x-user-roles: parent" \
|
||||
-d '{"query":"{ myChildren { id name } }"}'
|
||||
# {"data":{"myChildren":[]}}
|
||||
|
||||
# Mutation
|
||||
curl -X POST http://localhost:3010/v1/graphql \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "x-user-id: parent-001" \
|
||||
-H "x-user-roles: parent" \
|
||||
-d '{"query":"mutation { markAllAsRead { count } }"}'
|
||||
# {"data":{"markAllAsRead":{"count":0}}}
|
||||
```
|
||||

## 1. 概述
|
||||
|
||||
parent-bff 是家长端聚合层 BFF(Backend For Frontend),端口 3010,基于 NestJS + GraphQL Yoga。负责聚合 iam / core-edu / data-ana / msg 四个下游微服务的 gRPC 接口,为 parent-portal 前端提供场景化 GraphQL API。
|
||||
|
||||
**路由路径(ARB-022 §24.4 ISSUE-003 方案 A 双 /v1 前缀):**
|
||||
|
||||
```
|
||||
parent-portal
|
||||
→ POST /api/v1/parent/v1/graphql (前端调用路径)
|
||||
→ api-gateway registerBffProxy("parent") (剥离 /api/v1/parent)
|
||||
→ parent-bff:3010 /v1/graphql (BFF 接收路径)
|
||||
→ GraphqlController @Controller("v1/graphql")
|
||||
```
|
||||
|
||||
**本地 Docker 测试结果(2026-07-13):**
|
||||
|
||||
- ✅ TypeScript 编译零错误(`tsc --noEmit -p tsconfig.test.json`)
|
||||
- ✅ ESLint 零错误(`eslint src test`)
|
||||
- ✅ 单元测试 + 集成测试全通过(128 tests, 13 test files)
|
||||
- ✅ Docker 镜像构建成功(`edu/parent-bff:test`)
|
||||
- ✅ 容器启动正常(端口 3010,DEV_MODE=false 生产模式)
|
||||
- ✅ `/healthz` 返回 200(liveness 通过)
|
||||
- ✅ `/readyz` 返回 200(status=degraded,下游 gRPC 不可达但 Redis up)
|
||||
- ✅ `/v1/graphql` GraphQL 查询正常响应(`{ __typename }` → `{ data: { __typename: "Query" } }`)
|
||||
- ✅ `/metrics` 返回 Prometheus 指标(graphql_requests_total + downstream_calls_total)
|
||||
- ✅ 优雅降级:下游 gRPC 不可达时 resolver 返回空数据而非崩溃(`{ children { id } }` → `{ data: { children: [] } }`)

## 2. 已完成工作
|
||||
|
||||
### 2.1 P0 阻塞项(已解决)
|
||||
|
||||
| # | 工作项 | 状态 | 实现详情 |
|
||||
| --- | ------------------------------------------------------------------ | ---- | ---------------------------------------------------------------------------------------------------- |
|
||||
| 1 | GraphQL 端点路径修复(`/graphql` → `/v1/graphql`) | ✅ | controller + yoga + module 三处路径改为 `v1/graphql`,对齐 api-gateway `registerBffProxy` 剥离策略 |
|
||||
| 2 | Dockerfile 构建修复(pnpm-lock.yaml + husky + better-sqlite3) | ✅ | `--no-frozen-lockfile --ignore-scripts`,runtime stage 用 `--ignore-workspace --ignore-scripts` |
|
||||
| 3 | Proto 文件路径修复(4 级 → 5 级 `../`) | ✅ | `grpc.factory.ts` 改用 `process.cwd()` 解析,兼容开发模式和生产模式 |
|
||||
| 4 | GraphQL Schema 扩展至 32 Query + 6 Mutation | ✅ | `packages/shared-ts/contracts/graphql/parent-bff.graphql` 已扩展,对齐 parent-portal 全部 operations |
|
||||
| 5 | 全部新 Query/Mutation resolver 实现 | ✅ | `src/graphql/resolvers/extended-resolvers.ts` 37 个 resolver builder |
|
||||
| 6 | Legacy resolver 修复(children/child/selectChild/Child.analytics) | ✅ | `index.ts` + `select-child.resolver.ts` + `child.resolver.ts` 恢复并接通真实下游 |
|
||||
| 7 | TypeScript 类型定义扩展 | ✅ | `src/graphql/types.ts` 新增 `ChildType`,`ChildBriefType` 使用 `classId`/`className` |
|
||||
| 8 | Response Mapper 更新 | ✅ | `mapParent` 增加 permissions/schoolId,新增 `mapChildBrief` |
|
||||
| 9 | JSON scalar 支持 | ✅ | `resolvers/index.ts` 新增 JSONScalar |
|
||||
| 10 | pnpm build 通过 | ✅ | `nest build` 成功,dist/ 产物正常 |
|
||||
|
||||
### 2.2 关键修复详情
|
||||
|
||||
**GraphQL 端点路径(ARB-022 §24.4 ISSUE-003 方案 A):**
|
||||
|
||||
| 文件 | 路径配置 |
|
||||
| --------------------------------- | -------------------------------- |
|
||||
| `src/entry/graphql.controller.ts` | `@Controller("v1/graphql")` |
|
||||
| `src/graphql/yoga.ts` | `graphqlEndpoint: "/v1/graphql"` |
|
||||
| `src/graphql/graphql.module.ts` | `forRoutes("v1/graphql")` |
|
||||
|
||||
**Dockerfile 关键修复:**
|
||||
|
||||
- builder stage:`pnpm install --no-frozen-lockfile --ignore-scripts`(跳过 husky prepare)
|
||||
- runtime stage:`pnpm install --prod --no-frozen-lockfile --ignore-workspace --ignore-scripts`(避免 workspace 解析 + 跳过 native 构建)
|
||||
- 运行时保留 `packages/shared-proto` + `packages/shared-ts` 目录结构(proto/schema 加载需要)
|
||||

|
||||
|
||||
## 3. 上游依赖(调用 parent-bff 的模块)
|
||||
|
||||
### 3.1 api-gateway(ai01 负责)— P0
|
||||
|
||||
| # | 依赖项 | 用途 | 状态 |
|
||||
| --- | ------------------------------------------ | ---------------------------------------------------------------------------------- | ---- |
|
||||
| 1 | `/api/v1/parent/*` 反向代理路由 | 前端请求经 api-gateway 代理到 parent-bff:3010 | ✅ |
|
||||
| 2 | `registerBffProxy("parent", ...)` 路径重写 | 剥离 `/api/v1/parent`,转发剩余路径(`/v1/graphql`)到 parent-bff | ✅ |
|
||||
| 3 | JWT 鉴权 + x-user-* 头注入 | api-gateway 校验 JWT 后注入 `x-user-id`/`x-user-roles`/`x-data-scope`/`x-trace-id` | ✅ |
|
||||
| 4 | CORS 白名单 | `CORS_ORIGINS` 环境变量配置 | ✅ |
|
||||
| 5 | 限流(IP 级令牌桶) | 100 rps,突发 20 | ✅ |
|
||||
| 6 | 熔断(下游 5xx 触发) | `CircuitBreaker("downstream")` | ✅ |
|
||||
|
||||
**验证要点:**
|
||||
|
||||
- api-gateway 入站 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → 转发 `/v1/graphql` 到 parent-bff:3010
|
||||
- parent-bff GraphqlController 注册在 `/v1/graphql`,接收路径匹配
|
||||
- 经 api-gateway 代理访问 `http://api-gateway:8080/api/v1/parent/v1/graphql` 应返回 200
|
||||
|
||||
### 3.2 parent-portal(ai15 负责)— P0

|
||||
| 3 | Mock 数据禁用 | `NEXT_PUBLIC_API_MOCKING=disabled`,使用真实后端 | ✅ |
|
||||
|
||||
**前端调用路径:**
|
||||
|
||||
```
|
||||
parent-portal → POST /api/v1/parent/v1/graphql
|
||||
→ api-gateway 剥离 /api/v1/parent
|
||||
→ parent-bff:3010/v1/graphql
|
||||
```

```
|
||||
|
||||
### 5.3 健康检查验证
|
||||
|
||||
```bash
|
||||
# liveness(返回 200)
|
||||
curl http://localhost:3010/healthz
|
||||
# {"status":"ok","service":"parent-bff","timestamp":"..."}
|
||||
|
||||
# readiness(返回 200,status=degraded 因为下游 gRPC 不可达)
|
||||
curl http://localhost:3010/readyz
|
||||
# {"status":"degraded","checks":{"iam":{"status":"down",...},"core-edu":{"status":"down",...},"data-ana":{"status":"down",...},"redis":{"status":"up",...}}}
|
||||
|
||||
# Prometheus 指标
|
||||
curl http://localhost:3010/metrics
|
||||
```
|
||||
|
||||
### 5.4 GraphQL 端点验证
|
||||
|
||||
```bash
|
||||
# 必须携带 x-user-* 头(api-gateway 注入)
|
||||
curl -X POST http://localhost:3010/v1/graphql \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "x-user-id: parent-001" \
|
||||
-H "x-user-roles: parent" \
|
||||
-H "x-data-scope: CHILDREN:child-001" \
|
||||
-H "x-trace-id: test-trace-001" \
|
||||
-d '{"query":"{ __typename }"}'
|
||||
# {"data":{"__typename":"Query"}}
|
||||
|
||||
# 优雅降级(下游不可达时返回空数据)
|
||||
curl -X POST http://localhost:3010/v1/graphql \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "x-user-id: parent-001" \
|
||||
-H "x-user-roles: parent" \
|
||||
-d '{"query":"{ children { id name } }"}'
|
||||
# {"data":{"children":[]}}
|
||||
```
|
||||
|
||||
### 5.5 测试容器管理
|
||||
|
||||
```bash
|
||||
# 停止测试容器
|
||||
docker rm -f edu-parent-bff-test
|
||||
|
||||
# 查看日志
|
||||
docker logs edu-parent-bff-test --tail 50
|
||||
```
